- Scope
- This standard specifies the terms and definitions of seawater gravity cages, hydrological environment investigation, general design principles, floating frame system design, net clothing system design and anchoring system design requirements. This standard is applicable to the structural design of seawater gravity cages whose frames are made of high-density polyethylene pipes or galvanized steel pipes and float on the water. It is suitable for polyethylene pipe frame cages whose seawater depth is less than 20m and whose circumference is less than 120m. Box or galvanized steel pipe frame cage with a circumference less than 60m. The design of other seawater cages of the same type can be implemented as a reference.
